 To replicate:

 1) Add layer
 2) open python console
 {{{
 l = qgis.utils.iface.mapCanvas().layer(0)
 print l.isUsingRendererV2()
 ren = l.rendererV2()
 }}}
 3) edit symbology of layer with console open
 4) type 'print ren' in console again... crash

 The object no longer exists and should be returned as None rather than
 crashing QGIS.
